2024 Lexus Tx

I am reporting a severe, systemic vehicle performance discrepancy on my Lexus TX 500h (2.4L Turbo Hybrid powertrain). The vehicle is officially labeled with an EPA rating of 27 MPG combined. However, under normal, conservative driving conditions, the vehicle routinely achieves only 20 to 21 MPG—a consistent 20%+ shortfall from the manufacturer's certified window sticker metrics. This has drastically limited the vehicle's safe total driving range to under 300 miles per tank. The shortfall persists despite cautious driving in Eco Mode and after passing the engine break-in period. This issue matches a widespread pattern reported by numerous other owners in consumer forums, pointing to a potential defect in the vehicle’s fuel management software or hybrid battery management logic. I request that NHTSA log this tracking data to investigate whether the manufacturer misrepresented the vehicle's real-world operational capabilities or fuel-system integration.

Strong smell of gas coming from around the car and near rear end of car. Usually after a drive. The smell does not happen after every drive. I brought up the smell to my husband a number of times within the year…and finally took to JD Auto in Arizona in June but the gas smell could not be replicated and no source or defect could be visually seen. No recall for this has been reported by Lexus. dealership. No check engine light has been recorded. Worried that there is some internal issue that could cause huge problems. I do have children who have also reported smelling the gas in the back seat.

I am a loyal Lexus owner since 1998 and have always recommended Lexus vehicles to my family and friends. In over 25 years of ownership, I have never experienced an issue like this. While driving under normal road conditions, my new 2024 RX 350’s AC condenser was punctured by small road debris, causing a refrigerant leak and loss of air conditioning. The condenser is located directly behind the front bumper, leaving it exposed to minor debris, which I believe is a design vulnerability. Damage at such low mileage suggests this may affect other vehicles of this model. Reduced AC performance could impact driver comfort and visibility in extreme heat, and operating the system with low refrigerant may cause further mechanical damage. I am submitting this complaint to request that NHTSA review this as a potential design defect affecting multiple vehicles. I have also contacted Lexus for warranty repair.
